Liquify makes it possible. All you do: Have someone concentrate on a thought. Ask them to imagine their glass of water as a crystal ball and to focus their thoughts into it (you're probably already coming up with your own presentation). Tearing a corner from a piece of paper, you ask the spectator to dip the paper into the water.
Instantly, yet slowly and eerily, like a scene from a horror movie ... THEIR THOUGHT APPEARS ON THE PAPER!
Liquify is self working, there are no angle restrictions and it's always ready to go! This blistering effect is from Richard Sanders and Bill Abbott.
